The Princess Diaries
Mia Thermopolis's life changes when she discovers she is the heir to the throne of Genovia. This YA series follows her humorous and sometimes awkward journey as she navigates high school, friendships, romance, and royal training, all while trying to maintain a normal teenage existence.
The Princess Diaries series was adapted into two popular live-action films by Disney, starring Anne Hathaway as Mia Thermopolis and Julie Andrews as Queen Clarisse Renaldi. The first film covers events from the early books, while the second film introduces an original storyline.
Yes, there is a spin-off series called From the Notebooks of a Middle School Princess, which follows Mia's younger half-sister, Olivia Grace Clarisse Mignonette Harrison. This series is aimed at a younger middle-grade audience.
The main series should be read in numerical order from The Princess Diaries to Royal Wedding. There are also several holiday novellas, such as Princess Lessons and The Princess Present, which are best read between the earlier main series books.
